Incrucisari inerspecifice

  • Am gasit un articol foarte interesant depsre incercari de incrucisari intre specii ale sinningiilor.

    http://www.gesneriadsociety.org/gleanings/DOCS/Gleanings2013.01.pdf

    Pe pagina doi, se numeste: "Adventures in Hybridizing for Peloric Sunningias" de catre Ruth Coulson din Balcolyn, Australia.

    Peloric inseamna cu florile in sus, adica privesc in sus, nu atarna.

    Around twenty years ago a group to which I belong held a Gesneriad Display in a big lathcovered
    fernery at a large nursery in the west of Sydney. It turned out to be a weekend of
    the hottest conditions for many years.
    It was noticeable that large soft flowers were most damaged by the hot dry conditions.
    Large-flowered Achimenes and Sinningia speciosa flowers suffered most. Sinningias like
    Sinningia cardinalis and its different forms, Sinningia iarae and Sinningia glazioviana,
    suffered very little damage. I decided right then not to grow too many varieties of S.
    speciosa but to concentrate on those that proved themselves tougher and more resilient. We
    were already growing S. cardinalis 'Skydiver' and S. cardinalis 'George Kalmbacher'. I
    wondered whether it was possible to breed from these to get plants with larger and more
    open flowers that might not rival the size of S. speciosa varieties, but would at least be upfacing
    and display their centers and
    markings.
    I worked on that sporadically for a
    while, but since 2000 have done quite
    a lot of hybridizing. I am not sure I
    would have started on this path had I
    realized just how many generations
    would be needed. I am now up to
    cross number 176 and still going.
    Although I have mainly concentrated
    on Sinningia species like S. cardinalis,
    S. iarae, S. glazioviana and so on and
    my own hybrids from them, from time
    to time I cross out to other species to
    introduce new characteristics. Such a
    cross was to Sinningia globulosa. I
    like the idea of this very hairy plant.
    The initial plants from crossing a
    peloric Sinningia with S. globulosa
    were all zygomorphic and all orange
    shades from pale apricot to quite
    dark. All the plants were mighty
    plants. Sinningia globulosa is
    beautiful with its strong stems, bright
    flowers and hairs covering all. I find it
    needs plenty of light, preferring some
    hours per day of direct sun, to keep
    its stems sturdy. These initial hybrids
    needed at least as much sun but still
    grew very large. I finally retained
    only a couple of them in pots. I do
    have quite a few around the garden
    where they do very well indeed. .....
